Changes in the original public beta:

Startup check for critical ES updates. Added support for the server to automatically check for critical EventScripts versions. You can disable this by adding eventscripts_checkforupdates 0 to your autoexec.cfg. (Thanks to Venjax for coding the ES update server.)

NEW Changes in v2.1.1.338:

Fixes:

Major fixes for event handling in Orangebox (due to Valve's ServerCommand() regression)

Resolves GunGame crashes with server_cvar events (e.g. sm_nextmap)

Resolves GunGame and WCS problems when using custom events

Note: You must leave sv_allow_wait_command at its default value of 1. See Known Issues.

Fixed es.give(), es.setpos(), es.setang(), es.prop_physics_create(), etc, to execute properly when more than one used per tick

Created new versions of es.menu and es.dbgmsg to avoid CCommand overrun messages and lost menus

Configlib misexecution resolved by es.mexec() rewritten in Python and fixed (Thanks to freddukes and SuperDave)

Resolved odd characters and other problems with usermsg in CS:S (Thanks to XE_ManUp)
